The first officer disembarked at the main terminal, leaving the captain to taxi the aircraft to the south side of the airport. In good weather conditions, this would probably not have been a problem. However, since the captain needed to use the wind screen wipers while manoeuvring, he was required to lean across the cockpit, taking his attention away from his primary task of taxiing the aircraft. The operation of the wind screen wipers was carried out at a critical moment, and he missed the turn onto taxiway Charlie and the do-not-enter signs for Charlie 2. Calgary Airport Authority, Transport Canada, and NAV CANADA are aware that the Charlie 2 and Charlie intersection is a known confusion area. Numerous meetings and discussions have taken place to try to improve the situation at this intersection.Analysis The first officer disembarked at the main terminal, leaving the captain to taxi the aircraft to the south side of the airport.

The pilot was distracted from his primary task when he activated the wind screen wipers and inadvertently entered taxiway Charlie 2. The pilot was taxiing without the assistance of a second crew member. The use of reverse thrust caused snow to be blown onto the wind screen, thus requiring the use of the wind screen wipers.Findings as to Causes and Contributing Factors The pilot was distracted from his primary task when he activated the wind screen wipers and inadvertently entered taxiway Charlie 2. The pilot was taxiing without the assistance of a second crew member. The use of reverse thrust caused snow to be blown onto the wind screen, thus requiring the use of the wind screen wipers. In the months preceding and following this occurrence, NAV CANADA met with airport authorities and clients across Canada to discuss and study runway incursion problems. Upon completion of the study, NAV CANADA plans to make recommendations to reduce or eliminate these types of mishaps. TC participated in this study. In July 1999, TC formed a sub-committee of the National Civil Aviation Safety Committee to study further the issue of runway incursions. The final report of the sub-committee has been published (as National Civil Aviation Safety Committee, Sub-Committee on Runway Incursions, Final Report, September 14, 2000); it contains 23 recommendations for immediate and long-term action to address the issue of runway incursions.Safety Action Taken In the months preceding and following this occurrence, NAV CANADA met with airport authorities and clients across Canada to discuss and study runway incursion problems.
